Embodiment 1

[0034] Due to the increase in the number of days of smog and the concentration of smog in some areas, the visibility on the road has decreased, making it difficult for drivers to see the original traffic signs, resulting in an increase in traffic accidents. The luminescent plastic traffic signs made of luminescent plastics containing long-lasting luminescent materials can emit light to increase the power generation of copper indium gallium selenide thin film solar cells, and the current output from copper indium gallium selenide thin film solar cells is input to the controller through conductive wires After adjustment, the current output from the controller supplies power to the T-shaped sign LED lighting module through the conductive wire for lighting. When the light is insufficient, the photosensitive self-control switch is automatically turned on and the circuit is connected. The current output from the lithium-ion battery supplies power to the T-shaped LED light-emitting mo...

Embodiment 2

[0036] Due to the increase in the number of days of smog and the concentration of smog in some areas, the visibility on the road has decreased, making it difficult for drivers to see the original traffic signs, resulting in an increase in traffic accidents. The luminescent plastic traffic signs made of luminescent plastics containing long-lasting luminescent materials can emit light to increase the power generation of polysilicon thin film solar cells. The output current supplies power to the T-shaped sign LED lighting module through the conductive wire for lighting. When the light is insufficient, the photosensitive self-control switch is automatically turned on and the circuit is connected. The current output from the lithium-ion battery supplies power to the T-shaped LED light-emitting module through the conductive wire and the photosensitive self-control switch to ensure a certain brightness so that the driver can see the driving clearly.

Abstract

The invention relates to an illumination device applying a thin film solar battery to a luminous plastic traffic sign board, and belongs to the technical field of new energy source power generation culture. Through the increase of haze days and haze concentration in partial regions, the visibility on roads is reduced, so drivers cannot clearly see the original traffic sign boards, and the traffic accident increase is caused. The luminous plastic traffic sign board made of luminous plastics made of long-afterglow luminous materials can emit light rays to increase the power generating quantity of the thin film solar battery, current output from the thin film solar battery is input into a controller to be regulated through a conducting wire, and current output from the controller realizes the power supply and illumination to a T-shaped sign LED (light emitting diode) luminous module through a conducting wire. When the illumination is insufficient, a photosensitive self control switch is automatically switched on, and the circuit is conducted. The current output from a lithium-ion battery realizes the supplementary power supply to the T-shaped sign LED luminous module through the conducting wire and the photosensitive self control switch, and certain brightness is ensured, so the drivers can clearly see signs on the sign board.

Description

technical field [0001] The invention relates to a lighting device in which a thin-film solar cell is applied to a luminescent plastic traffic signboard, and belongs to the technical field of new energy power generation culture. Background technique [0002] In 2013, the national average number of smog days reached the highest in 52 years. Nanjing had 186 smog days in 2013, and the number of smog days in Beijing, Tianjin, Hebei, Zhengzhou, Shanghai and other places was higher than in previous years. The impact of human factors on the environment is the root cause of the current high incidence of haze days. High energy consumption, high emissions, and high pollution of coal-fired power generation, steel, chemicals, and automobile exhaust, dust from construction sites in cities, and straw burning in rural areas are all sources of environmental pollution and smog. On January 7, 2014, the Yangtze River Delta Regional Air Pollution Prevention and Control Cooperation Mechanism, co...
